A series of novel soluble nature-inspired flavin derivatives substituted with short butyl and bulky ethyl-adamantyl alkyl groups was prepared via simple and straightforward synthetic approach with moderate to good yields. The comprehensive characterization of the materials, to assess their application potential, has demonstrated that the modification of the conjugated flavin core enables delicate tuning of the absorption and emission properties, optical bandgap, frontier molecular orbital energies, melting points, and thermal stability. Moreover, the thin films prepared thereof exhibit smooth and homogeneous morphology with generally high stability over time.
通过简单直接的合成方法，制备了一系列新型可溶性的受自然启发的黄素衍生物，其中含有短的丁基和大体积的乙基-金刚烷基烷基取代基，产率中等至良好。对材料进行了全面的表征，以评估其应用潜力，结果表明，对共轭黄素核心的修饰能够精细调节吸收和发射特性、光学带隙、前沿分子轨道能量、熔点和热稳定性。此外，所制备的薄膜具有光滑均匀的形态，通常随着时间的推移具有较高的稳定性。
